We were a little frustrated with this product when we tried to screw in the pieces and the screw just SNAPPED. We went out and bought all new screws, because we were afraid of our cat getting up there, laying in the round "house" like area and it falling down because another screw snapped. We were very annoyed and almost sent the product back, but the items themselves seem fine. I would highly suggest getting new screws and brackets if you purchase this item.
